To all whom it may concern.'

Be it known that I, 'Groen F. Voici-rr, a citizen of the United States, residingat San Francisco, in the county of San Francisco and State of California, have invented a new and. useful Lubricating Device for Springs, of which the following is a specification.

The present invention relates to improve ments in lubricating devices for leaf springs, one object of the invention, being the provision of means whereby th'e leaves of the springs where the same contact, are forced apart and lubricant is injected therebetween., the lubricantJ thus preventing the rusting between the springs and at the same time reducing the friction between the leaves when the tension is placed upon them and relieved.

A. further object. of the presentinvention, is the provision of a novel means, whereby the leaves of the springs are lirst separated and a proper spacing'is produced to permit of the introduction of the lubricant therebetween, there being provided for this purpose, two prying members, for introduction'between thc leaves at opposite points, one ofthe wedging members being connected to a lubricating device by means of which the lubricant is injected through the wedging. member between the leaves.

With the foregoing and lother objects in view which will appear as the description proceeds, the invention resides in the combinationl and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a side elevation partly in section of the preferred form of the present device. Fig. 2 is a topl plan View thereof with a portion of the leaf spring broken away to show the parts in the Inkoper position. Fig aview in elevation and partly in section of a modified form of the present invention. Figs. f1, o and (l are detail views of parts of the devices shown in Fig. 3. Fig. 7 is a view similar to Fig'. of another modified form of lubricating de vice. Figs. 8, 9 and l() are detail views of various parts of the device shoi'n in Fig. 7. Fig. ll is a wicw similar to Fig. 3 of another modified form of thc present invention. Fig.

l2 is a section taken on line 12-12 of Fig. 1l. Fig. 13 is a section taken on line -13--13 of Figli. Fig. 14 is a detail view of the device as shown in Fig. 1v1. Fig. 15 is a de- Ltailview of still another modifie form of the present invention. Figs. 16, 17 and 18 are detail views of the device as shown in Fig. 15. 'v

Referring to thedrawings, and more particularly to Figs. 1 and 2 thereof, the numeral It designates a yoke frame which, as shown, is provided with the terminal 2 threaded' at 3 to receive the feed screw 4.-. This feed screw 4 is provided with the pointed prying end 5 and with the manipulating winged member 6. The terminal 8 is disposed in parallel with the terminal 2 and, as shown, is provided with the tixed or integral prying member 9 which, as shown, is tapered toward its prying end and is prof vided with the centrally disposed recess or notch 10. Formed through the 1body of the prying membei` 9 and in communication with the notch 10, is a duct or channel 11:, which leads to the threaded portion 12 which receives the reduced end 13 of the lubricant cup 14C. The member 15 of the lubricating device is disposed as in the usual form of grease cups, so that the same may be operated to cause the forcible ejection of the lubricant through the duct 11 and the notch 10 of theI prying device 9 into the space 7. between the respective leaves of the spring S. lt will .thus be seen that with the pres` ent device, the terminals Q and 8 may be disposed at each side of a leaf spring, so that the prying member 9 will be disposed first at one side of the spring and that when' the feed screw Il is rotated to cause the cylindrical prying member 15 to be interposed between the same members of the spring, the respective leaves of the spring will be spaced apart tofp'goduce the space 7, as shown. in Fig. l, so *that when the lubricating cup 15 is rotated to cause the lubricant therewithin to be forced through the port 11, the recess or notched end 10 will permit' of the proper, introduction of the lubricant into the space 7, so that when the prying members are released from the leaf springs, the lubricant will be properly disposed upon the adjacent faces of the leaves of the springs. By this means it will be seen that* lubricant may be quickly and easily intro# duced between the leaves and that thus tho fes` lit

friction ,at such points will be greatly re-I f duced and consequently the life of the spring be increased. I

In Figs. 3, L1, 5 and 6, a slight modification of the present device is shown, the yoke 1 being provided with a xed prying point 9', while they feed screw 4', carrying the grease or lubricant supplying cup 15 and the manipulating handle 1.7, has disposed upon 'z its inner end, through the means ofthe pin and slot a-fa, the lubricant introducing tated through the medium of the disk hanr dle 17, and the proper necessary movement imparted to the member 16 through the con nection at o o between it and the screw L1.

In the form of device shown in Figs. 7, 8, 9 and 10, a projection 19 is carried by the yoke and is soclreted to receive the lubricant supplying and prying member 16, which is made somewhat similar to the member 16 and is provided with the lubricant directing 'notch 10a in its forward reduced edge.

its en'ds, the lubricant cup 14a. which forms a handle for rotating the screw 4*, the plunger 15 for the lubricant being disposed within the cup so that the lubricant 1s properly ejected through the prying lubricating member 16 which is disposed to aline with the iixed prying member 91 of the deyice. A groove and pin connection h-Zi connects the prying head 16 with the screw d and thus provides a means whereby the screw ia may be rotated without rotating the inember 16. rEhe groove b and the two parallel pins h, as illustrated in Fig. 19- are employed to hold the prying member 16 to the screw Lia, so that the screw e may be rotated without imparting rotation to the member 16.

In the form of device shown in Figs, 11, 12 13 and ,14,va cylindrical bar or rod 2O is employed zand has attached to one end, the upstanding arm` 21 provided with the stationary spring prying wedge member 22 and `the opposite end with the-'arm 23, provided for the reception of the feed screw 4b. Disposed upon the rod 2() between the arms 21 and 23 for sliding movement is the aim 24, which c rries at its opposite upper end, the lubricant supplying and prying member 2d which iscprovided with the notch 10b similar' to the notch 10 of the device shown'in Fig.

The screw e which corresponds to the screw 1 is mounted 1n the member 19 and carries upon and 18, a cylindrical stem 26 is rovider 'ind carries at one end the upstan .ing arm 27 provided with the fixed prying member 28, the opposite end 29 beingthreaded for the reception ot the operating wing nut 30. Disposed for sliding movement upon 4the stem 26 is a sleeve 31, which carries the arm 32. This arm 32 is provided with the enlarged upper end 32 and with the forward recessed rib or projection 33 formed integral therewith. A port 34 is provided in the end 32 and leads into the thfeadedfsoclet 35 for the reception of the threaded connection 36 of the lubricant supplying device 37. The lubricant supplying and prying point or member 3S, in the present instance, is composed or a di'erent material, preferably a harder or more highly tempered metal than the arm 32, and is attached to the lug 33 through means of the rivets orscrews 39. A channel or port l0 is provided in the inember 38 and the same is disposed to aline with the channel 3e, so that lubricant may be supplied :from the member 37 through the notch 10, which is formed in the reduced prying end of the member 38 similar to the notches heretofore described in the other members.

From the foregoing description, taken in connect-ion with the drawings it is evident that forms of the present device embody oppositely disposed means i'or erted to pry the leaves of the springs apart before the final introduction of the lubricant therebetween.

W'hat is claimed is:

1. A leaf springy separator and lubricator,

including two oppositely disposed spring` engaging and prying members, means. forV moving one member to and from the other member, one of said prying members at its 'free en d being provided with a lubricant intr'oducing notch, and a lubricant supplying rying or kseparating the various leaves of t e spring,
